Live 9

Install the driver on your system. Please note that after installing the driver, it might be necessary to restart your computer in order to finish the installation.

Connect the Launchpad to your computer and start Live. The correct Control Surface should already be automatically selected. In case this does not happen or you need to change it:

Open Live's Preferences (CTRL+, / CMD+,) and show the MIDI/Sync tab.

In one of the available Control Surface choosers, select the Launchpad which matches your device. Please note: The MK2 and Pro have their own listings, for the MK1, Mini, and S use the "Launchpad" option.

In the related Input and Output choosers, select Launchpad as well:

Make sure that the MIDI ports for the Launchpad are configured correctly. Enable "Track" and "Remote" for the Launchpad's inputs and outputs.

For the Launchpad MK2 and Pro, you will also need to enable the output Sync port.

Live 8

In Live 8 there is only one Launchpad Control Surface available, called simply "Launchpad". This supports the MK1, Mini, and S models. The MK2 or Pro are not supported.
